North America's Role in ALMA

North America's contributions to ALMA include:

  • The North American ALMA Science Center, ALMA "headquarters" for North America
  • Receiver cartridges for ALMA bands 3 and 6
  • An ALMA "Front End Integration Center" where receiver cartridges from around the world are integrated into large cabinets that are then shipped to Chile for installation into antennas
  • At least twenty-five 12-meter antennas
  • ALMA's photonic local oscillator
  • Digital electronics for transmitting signals from the antennas
  • The correlator for the 12-meter array
  • The Array Operations Site (AOS) technical building, second highest steel frame building in the world
  • Road and power distribution to the AOS
  • A variety of tools, including the Common Astronomy Software Applications (CASA) tool, Simdata, and Splatalogue.
